Abstract

PURPOSE:To fit a seat belt to any rider in physique so well by setting up a shoulder belt anchor part in the more inner part than a lap belt anchor part. CONSTITUTION:A freely turnable flange 14 is set up in an upper side frame 13a being twisted inward a side frame 13 of a seat back frame 2, forming an anchor part 14 of a shoilder belt part 15. Then, this anchor part 14 of the shoulder belt part 15 is set up in the more inner part as far as l than an anchor part 9 of a lap belt part, while the anchor part 14 is set up at the side of a headrest 16. With this constitution, a belt 7 is deliverable from just the side of the headrest 16, so that the belt 7 can be set to any rider in physique along his shoulder. In addition, the lap belt anchor part 9 can bind any waist of the rider to be settled in a seat owing to a lap belt 8.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt-integrated seat device having a built-in type seat belt structure in which all the support members of the seat belt are incorporated into the seat side.

2. Description of the Related Art As the speed and acceleration of an axle increases, the amount of gravity (G) that acts on an occupant in the event of a collision or collision also increases. Particularly in the case of a frontal collision, it is necessary to reduce the deceleration to the occupants to prevent them from being thrown against the windshield or ejected from the vehicle.

[0003] Seat belts and airbags are installed in vehicles as measures to prevent and cushion the impact of such accidents and secondary disasters associated with such accidents. A typical seat belt has a structure in which a lap belt for lumbar region restraint and a shoulder belt for upper torso restraint are integrally combined. Furthermore, an airbag is placed between the occupant and the steering wheel or instrument panel by inflating the bag with gas, and the bag absorbs the movements of the occupant during a collision, thereby reducing secondary disasters.

[0004] By the way, the above-mentioned seat belt has its retractor (means for allowing the seat belt to move in and out freely during normal times to ensure the movement of the occupant, and tensioning the belt only in an emergency to restrain the occupant) to the pillar of the vehicle body. There are fixed types and built-in types built into the seat itself. With the built-in type seatbelt structure, the relative relationship of the seatbelt to the occupant does not change regardless of the degree of inclination of the seatback or the change in the longitudinal position of the seat cushion, so the preferred belt position relative to the occupant can be maintained. has advantages.

[0005] The built-in type seat belt structure is

45 Publication, Utility Model Publication No. 2-33740, German Publication No. 3,932,622, and German Patent No. 3,613
, 830, various types have been proposed.

By the way, as mentioned above, the built-in type, in which the retractor is attached directly to the seat claim, has many advantages over the one in which the retractor is attached to the pillar of the vehicle body, and is attracting attention. However, even such a device has the following problems. That is, even though the physiques of occupants who use such a built-in type seat belt structure, ie, a belt-integrated seat device vary widely, the belt position cannot be changed. Therefore, the belt position is adjusted to match the average physique. This causes problems such as the shoulder belt not fitting the shoulder of a person with a small body, and the lap belt digging into the waist of a person with a large body.

[0007]

[Problems to be Solved by the Invention] Therefore, the present invention
The problem to be solved is to eliminate the problems of the prior art described above.

[0008]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention focuses on the relative positional relationship between the shoulder belt anchor part and the lap belt anchor part, and makes the shoulder belt anchor part higher than the lap belt anchor part. Use means to position it inside.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Refer to FIG. A seat back frame 2 is connected to a seat cushion frame 1 via a reclining mechanism 3. Attach the seat slide mechanism 4 to the seat cushion frame 1. 5 is a mechanism for raising and lowering the front part of the seat cushion. An anchor part 9 at the tip of a lap belt part 8 of a seat belt 7 is fixed to one side plate 6 of a seat cushion frame 1. A buckle 11 is fixed to the other side plate 10, and a tongue plate 12 is attached to the buckle 11 so as to be slidable on the seat belt 7.
can be attached freely.

One side of the seat back frame 2 is a rectangular side frame 13 with a closed cross section, as shown in FIG. This side frame 13 is made up of channel-shaped members facing each other, and its upper part 13a is twisted inward (see FIG. 4). A rotatable flange 14 is disposed on this upper frame 13a, and forms an anchor part for a shoulder belt part 15. The retractor is fixed to the inside or side of the upper frame 13a.

Referring to FIG. 2. The anchor part 14 of the shoulder belt part 15 is disposed inward by I from the anchor part 9 of the lap belt part 8. Further, this anchor portion 14 is arranged on the side of the headrest 16. With this arrangement of the shoulder belt anchor portions 14, the belt 7 can be extended from the immediate side of the headrest 16, so that the belt 7 can be placed along the shoulders of an occupant of any size.

[0012] The lap belt anchor part 9, which is located outwardly by I from the shoulder belt anchor part 14, can restrain any lumbar part of the occupant that fits in the seat by the lap belt part 8.

The side surface 13b of the upper frame 13a is directed toward the buckle 11, and the belt 7 coming out of the anchor portion 14 is directed straight toward the buckle 11 without twisting. Therefore, the belt can be used within its maximum strength limits and still fits the occupant's shoulders.

[0014]

[Effects of the Invention] According to the present invention, the seat belt can effectively restrain the shoulders and lumbar region of people of any size, and
Since there is no twisting of the belt, the strength of the belt can be maximized.
